Carmelo Anthony nursing sore hamstring, Knicks send trainer to London

Carmelo Anthony is nursing a sore hamstring and although he maintains he's fine, the New York Knicks have sent a trainer to London to watch over him, according to a tweet Thursday from Frank Isola of The New York Daily News.

It's not certain whether he injured his hamstring on a specific play recently or if it's been something that has been nagging him for an extended period of time. He is averaging 17.3 points per game on 53-percent shooting at the Olympics, so it doesn't appear to have a real effect on his game.

His hamstring injury will be monitored by team trainers as the U.S. readies itself for a semifinal match against Argentina on Friday. Anthony took a shot to the groin on Monday from Facundo Campazzo of Argentina, prompting Anthony to say the dirty play was "uncalled for."

The winner of U.S.-Argentina will play for the gold in a game against the winner of Russia and Spain in the other semifinal.
